A systematic review of case reports in spontaneous regression of head and neck squamous cell carcinoma (SCC) was carried out to investigate the pattern and characteristics of this phenomenon.

A systematic search of case studies of spontaneously regressed head and neck SCC was carried out in Ovid Embase, Ovid Medline and Pubmed. Methodological quality was assessed by ascertainment of diagnosis and overall details of reports. Outcomes included patient demographics, head and neck SCC characteristics and clinical course of disease.

A total of 8 cases were included and 50 per cent (n = 4) of the reported cases were SCC of the vocal folds. All cases received a surgical biopsy and three cases had possible febrile episodes preceding regression. The mean length of time to regression was 4.3 months.

Spontaneous regression in head and neck SCC is likely to be under-reported. A better understanding of how the host immune system can instigate an antitumour response will shed light on the development of novel treatments.

In this study, we reviewed the post-operative complications in parotidectomy and its association with various patient, tumour and surgical factors.

All parotidectomies performed in our regional unit between 2013 to 2020 were identified. Electronic medical record and clinic letters were reviewed for any post-operative complications. A logistical regression model was applied on data collected on twelve patient factors, three tumour factors and four surgical factors.

379 cases of parotidectomy were identified in the eight-year study period. 55% (n = 210) were documented with nine types of post-operative complications. This study identified age >80 (odds ratio = 1.89, p = 0.018), active smoker (odds ratio = 0.94, p = 0.018), total parotidectomy approach (odds ratio = 1.77, p = 0.012), longer operation time (odds ratio = 0.006, p = 0.015) and hypertension (odds ratio = 1.23, p = 0.019) were associated with a higher risk of facial nerve palsy. Predictive factors were also identified for auricular nerve numbness and Frey syndrome.

This study revealed the incidences and potential predictors of post-operative complications in parotidectomy. Notably, the grade of operator (consultants/ registrars) had no effect on the possibility of adverse outcome, reflecting patient safety was not compromised for training. These findings can be used in patient counselling and guide treatment options to minimise post-operative complications.

During the coronavirus disease 2019 pandemic, ENT-UK recommended a move from face-to-face clinics to telephone appointments. This study reviewed the safety of telephone clinics for urgent two-week-wait cancer referrals.

Patients consulted in telephone clinics between April and November 2020 were identified from an electronic database. Study patients included those diagnosed with malignant disease at six months. The Head and Neck Cancer Risk Calculator version 2 score, outcome of the initial clinic and final diagnoses were reviewed.

A total of 1062 patients were triaged in clinic; 9.2 per cent (n = 98) were diagnosed with cancer at 6 months. Of these 98 patients, 69 received an urgent face-to-face appointment, 26 underwent urgent scans and 3 had a delayed telephone review. Twenty patients (20.4 per cent) diagnosed with cancer had a low-risk Head and Neck Cancer Risk Calculator score.

The late diagnosis rate of 0.28 per cent suggests a small proportion of cancer could have been missed. Telephone clinics, whilst a pragmatic means to maintain patient flow during the pandemic, could result in late diagnoses.

To evaluate the effects of disease severity, corticosteroids and social factors on neuropsychiatric complaints in severe acute respiratory syndrome (SARS) patients, both during acute and convalescent phases.

Self-administered mail questionnaires survey to 308 SARS patients after discharging from hospital. Both patients and their families were asked about symptoms related to various neuropsychiatric domains, and the questions covered both acute and convalescent phases.

Among the 102 (33%) valid replies, 65% had strong symptoms in convalescent phase as indicated by GHQ28 score ≥ 5. In multiple linear regression analysis, use of pulse steroid and total dosages of pulse steroid during hospitalisation were predictive for anxiety-depression, psychosis and behavioural symptoms in acute phase, the effects persisted in convalescent phase. Disease severity had direct correlation with symptoms in all neuropsychiatric domains at acute phase and anxiety-depression and cognition at convalescent phase. Health care workers had more neuropsychiatric complaints in both phases. Severity of symptoms, corticosteroids and social factors explained about half of the variances (R2 = 52) in anxiety-depression at acute phase and 33% at convalescent phase.

Severe disease, high dose corticosteroids and being health care workers were independent predictors of neuropsychiatric complaints in both acute and convalescent phases.
